TO ALL WHOM IT MAY CONCERN; A

Beit known that I, O. S. PEASE, of Xenia, in the county of Greene, and State of Ohio, have invented certain new and useful Improvements irrPadloeks; and I do hereby declare that the following is a full, clear, and exact' description thereof, reference being had to the accompanying drawings, and to the letters ofreference' marked thereon, which form a part of this specification, in which- Figure l is a plan view, with the upper side removed, showing the internal construction of the lock. Figure 2 is a plan of same, with the upp'er side in place.

Figure 3 is a central section, showing the position of the cartridges and seal when the lock is in actual use.` The nature of my invention consists in the cmploymentof cartridges as the means by which'the locleis secured, the said cartridges being so arranged that lin order to unlock the clasp it will be necessary to explode i the cartridges.

To enable others skill'edin the arts to'imake and us'e my invention, I subjoinithelfollowing .description of the same. l 4

A represents the casing, and B the clasp, which'is hinged in theusual manner.v The end of clasp B which enters the lock is furnished with a notch, t, as seen in Eg. I.

d designates the tumbler, the forward end of which is so shaped as to fit in notch t, above mentioned. The said tumbler is provided with a hole, e, which corresponds with a. similar hole in easing A,Aas seen in fig. 2.

The hole in the casing is furnished on cach side with a shoulder, g, the object of which will be moro fully seen hereafter.

n is a spring for operating tumbler fl.

It will be observed that the notch invthe cla-sp B is so formed that when the cartridge is removed from the hole in tumbler cZ, the clasp B may be easily drawn out.

C represents the device by which the cartridges are exploded and the lock opened.

The said device resembles in construction the pliers in common use, and having the two jaws perforated, one of the jaws having in its perforation the movable pin m. The said pin will serve the double purpose of pressing a. thin lead filling over each cartridge, and also assist in exploding tle cartridges by the aid of a pointed metal device to be lplaced in the perforation ofthe lower jaw of plier C. 'Y

When the cartridge or cartridges are inserted in holes e, and pressed together with the lead filling on top, and the clasp Bvheld in place by tumbler d, as described, it will be impossible to disengagc the said clasp, except by exploding'the said cartridges, and this willbc done by the'use of the pliers C.

IIaving thus described my invention, what I claim, and desire to secure by Letters Patent, is

A lock which will be secured by means of one or more cartridges when inserted throughfthe casing A and tumbler d, and which can be unlocked only by the explosion of thecartridgcs, in the manner substantially as described. A I

In testimony that I claim the foregoing as my own, I atlix my signature in presence of two witnesses.
